Natural Language Processing. Human-Computer Interaction. Software Engineering for Software as a Service. Design and Analysis of Algorithms I. About the Course In this course you will learn several fundamental principles of algorithm design.

Design and Analysis of Algorithms I

You'll learn the divide-and-conquer design paradigm, with applications to fast sorting, searching, and multiplication. Cryptography. Cryptography is an indispensable tool for protecting information in computer systems.


This course explains the inner workings of cryptographic primitives and how to correctly use them. Students will learn how to reason about the security of cryptographic constructions and how to apply this knowledge to real-world applications. The course begins with a detailed discussion of how two parties who have a shared secret key can communicate securely when a powerful adversary eavesdrops and tampers with traffic. We will examine many deployed protocols and analyze mistakes in existing systems. The second half of the course discusses public-key techniques that let two or more parties generate a shared secret key. The course will include written homeworks and programming labs. A preview of the course, including lectures and homework assignments, is available at this preview site.

Probabilistic Graphical Models. What are Probabilistic Graphical Models?

Probabilistic Graphical Models

Uncertainty is unavoidable in real-world applications: we can almost never predict with certainty what will happen in the future, and even in the present and the past, many important aspects of the world are not observed with certainty. Probability theory gives us the basic foundation to model our beliefs about the different possible states of the world, and to update these beliefs as new evidence is obtained. 30 Days to Learn jQuery. streaming your code to the masses.

SSH tricks. Why SSH?

SSH tricks

As recently as a 2001, it was not uncommon to log in to a remote Unix system using telnet. Telnet is just above netcat in protocol sophistication, which means that passwords were sent in the clear. As wifi proliferated, telnet went from security nuissance to security disaster. As an undergrad, I remember running ethereal (now wireshark) in the school commons area, snagging about a dozen root passwords in an hour. Backbone patterns. Here, I try to document the good practices that our team has learned along the way building Backbone applications.

Backbone patterns

Inline templates The problem: if you need to use view templates in a small Backbone application, defining your templates in JavaScript code will be unwieldy and difficult to maintain. Solution: You may need some view templates to be inline in the HTML page. This solution has been outlined by John Resig in his blog post about JavaScript micro templating. Defining inline templates You can put templates in an HTML <script> tag. Change the type attribute to something else so it will not be interpreted as JavaScript.Set an id so we can easily refer to it. Git - the simple guide - no deep shit!

BTW: I’m not very strict on the definition of “ebook”, some of them are really just HTML versions of books. [UPDATED: 2012-01-18] Addyosmani/backbone-fundamentals - GitHub. Code School. Efficient JavaScript. By Mark 'Tarquin' Wilton-Jones Traditionally, a Web page would not contain much scripting, or at least, not much that would affect the performance of that Web page.

Efficient JavaScript

However, as Web pages become more like applications, the performance of scripts is having a bigger effect. With more and more applications being developed using Web technologies, improving the performance of scripts is becoming increasingly important. With a desktop application, a compiler is normally used to convert the source into the final binary. The compiler can take its time, and optimize as much as possible for good performance of the final application.

Browsers are fairly good at achieving this, and Opera has one of the fastest scripting engines of any current browser. This article will show several simple changes that can be made to improve the performance of your Web applications. Quick Tips ECMAScript Document loading.

Python for the Web. YUI3 « Triptych. YUI3 is a modern javascript library that allows you to build cross-browser applications without having to worry about all of the issues you might run into with low level javascript coding. It provides a library of utilities as well as a host of best practices for web development. Needless to say I’m a big fan of YUI and I’ve written several articles about it over the past year or so. The Unix Command Line: Text Files. By Gordon Davisson Copyright (c) 2002, Westwind Computing inc. Working with Text Files: more and less - display the contents of a text file, one screenful at a time (hit the spacebar to get the next screen). Note that this only works well with plain text files, not Word files, RTF's, PDF's, or anything else that contains formatting information. less also allows you to go backwards (type "b") in the file.
